* NFC: add nfc subsystem coreLauro Ramos Venancio2011-07-052-13/+5
| | | | | | | | | | | The NFC subsystem core is responsible for providing the device driver interface. It is also responsible for providing an interface to the control operations and data exchange.

* drivers/nfc/pn544.c: add missing regulatorMatti J. Aaltonen2011-02-251-1/+3
| | | | | | | | | | | | | | | | | | The regulator framework is used for power management. The regulators are only named in the driver code, the actual control stuff is in the board file for each architecture or use case. The PN544 chip has three regulators that can be controlled or not - depending on the architecture where the chip is being used. So some of the regulators may not be controllable. In our current case the third regulator, which was missing from the code, went unnoticed because we didn't need to control it. To be as general as possible - in this respect - the driver needs to list all regulators. Then the board file can be used to actually set the usage. Signed-off-by: Matti J.

* NFC: Driver for NXP Semiconductors PN544 NFC chip.Matti J. Aaltonen2011-01-133-0/+926
Creates a new "Near Field Communication" subsystem in drivers/nfc. http://en.wikipedia.org/wiki/Near_Field_Communication is useful ;) This is a driver for the pn544 NFC device. The driver transfers ETSI messages between the device and the user space. Signed-off-by: Matti J.
